3  * index_selfuncs.h
4  * Index cost estimation functions for standard index access methods.

7  * Note: this is split out of selfuncs.h mainly to avoid importing all of the
8  * planner's data structures into the non-planner parts of the index AMs.
9  * If you make it depend on anything besides access/amapi.h, that's likely
10  * a mistake.
